 The Minimum Variance Unbiased Estimator
The first term on the right-hand side is called the variance of the estimator, and the second term on the right-hand side is the square of the bias of the estimator.
Since the bias depends on the value of the unknown parameter, it seems that any estimation criterion that depends on the bias would lead to an unrealizable estimator, as the previous example suggests (although in certain cases realizable minimum MSE estimators can be found).
Since the dependence of an estimator on the unknown parameter appears to come from the bias term, we hope that constraining the bias to be zero will lead to a useful design criterion.

 The Corrected Estimator
Graphs of the corrected estimator for m=3 and N=3000, generated by using coefficients found by solving the full systems in Equation (4), can be compared in Figures 9-12.
Also, the graphs cause one to doubt that the variance is under control since the estimators in Figures 9 and 12 exhibit very different behavior near the right-hand endpoint than those in 10 and 11.
But, even though the bias of the estimator is small everywhere, the variance on subintervals near the boundaries is large.

 Cost estimators
Construction cost estimators also may be employed by the project’s architect or owner to estimate costs or to track actual costs relative to bid specifications as the project develops.
When estimating the cost of developing a new product, for example, the estimator works with engineers, first reviewing blueprints or conceptual drawings to determine the machining operations, tools, gauges, and materials that would be required for the job.
Although estimators spend most of their time in an office, construction estimators must make visits to project worksites that can be dusty, dirty, and occasionally hazardous.

 SSRN-Multicollinearity and Modular Maximum Entropy Leuven Estimator by Sudhanshu Mishra
A high degree of multicollinearity often has a detrimental effects on the estimation of a linear econometric (regression) model due to an intricate internecine sharing among the estimated regression coefficients (beta).
This new estimator is not fully a la Paris (2001) and hence we name it as the Modular Maximum Entropy Leuven (MMEL) estimator.
We observe that overall, the performance of MMEL (in terms of mean estimated coefficients as well as the RMS values) is much superior to that of the MEL estimator.

 Estimator - Wikipedia, the free encyclopedia
It has been suggested that this article or section be merged with estimation theory.
In statistics, an estimator is a function of the observable sample data that is used to estimate an unknown population parameter; an estimate is the result from the actual application of the function to a particular set of data.
There are two types of estimators: point estimators and interval estimators.

 FAQ: Advantages of the robust variance estimator
The robust variance estimator is robust to the assumptions (1) and (2).
The robust variance estimator estimates V(b) such that nominal (1 − alpha) confidence intervals constructed from it have B in the interval about (1 − alpha) of the time if one was to repeatedly resample from this population.
The robust variance estimator produces correct variance estimates V(b*) for b* in the same sense discussed above: nominal (1 − alpha) confidence intervals constructed from it have B* in the interval about (1 − alpha) of the time if one were to repeatedly resample from this population.

 Minimum-variance unbiased estimator - Wikipedia, the free encyclopedia
In statistics, and more specifically in estimation theory, a minimum-variance unbiased estimator (MVUE or MVU estimator) is an unbiased estimator of parameters, whose variance is minimized for all values of the parameters.
In many cases, a biased estimator can have a uniformly smaller mean squared error than does any unbiased estimator of the same parameter.
Constructing such an estimator is often done by relying on the Rao-Blackwell theorem.
